I stuck it out and didn't test until this morning. This is what I got:
No mistaking that second line. It actually came up within 5 seconds so there is no doubt. I took this within 3 minutes and the line continued to darken. It is the same colour as the control line.
I had begun to suspect that I might get a BFP around Friday but still refused to test while I was on the road. I hadn't had any pre-AF spotting just like in February so I thought this might be a sign of a BFP. Then, I've been having crazy pain in my lower right pelvic area for about 4 days. I didn't know if that was from impending AF or if it was just a large corpus luteum.
I'm being cautiously optimistic at this point. My beta isn't until Tuesday so I have to wait for the exact numbers. But until then I'll be happy and cross my fingers that this one will stick!
